DZASUM

Function/Subroutine Documentation

  double precision function dzasum (integer n, complex*16, dimension(*) zx, integer incx)

DZASUM

Purpose:

    !>
    !>    DZASUM takes the sum of the (|Re(.)| + |Im(.)|)'s of a complex vector and
    !>    returns a double precision result.
    !>

Parameters
    N

    !>          N is INTEGER
    !>         number of elements in input vector(s)
    !>

    ZX

    !>          ZX is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
    !>

    INCX

    !>          INCX is INTEGER
    !>         storage spacing between elements of ZX
